Electro-optical optic sight

Abstract

An optic sight assembly for installation on a riffle is disclosed, comprising an electro-optical optic sight unit which comprises a controller unit, a remote control receiver, and an electro-optical unit to project a reticle image; and a corresponding remote control unit to control operational parameters of the electro-optical optic sight. The remote control unit comprises a remote control controller to produce control signals for transmitting to the remote control receiver, and a keypad unit to enable entering control commands to the remote control unit, wherein the electro-optical optic sight is adapted to receive control signals from the remote control unit to control operational parameters of the reticle.

The invention claimed is: 
     
       1. An optic sight assembly ( 100 ,  200 ) for installation on a rifle comprising:
 an electro-optical optic sight unit ( 102 ,  210 ) disposed at a rear part of the rifle comprising:
 a controller unit ( 211 ); 
 a remote control receiver ( 222 ); and 
 an electro-optical unit ( 234 ) to project a reticle image; 
 a casing; 
 at least one first control button ( 216 ,  330 A/ 330 C) disposed on at least one inclined facet ( 302 C 1 / 302 C 2 ) on a rear side of the casing, wherein the facet is inclined by an angle α from a plane perpendicular to a longitudinal line of the optic sight assembly; and 
 
 a corresponding remote control unit ( 104 ,  260 ) disposed at a front part of the rifle comprising:
 a remote control controller ( 270 ); 
 a remote control transmitter ( 280 ) to transmit control signals to the remote control receiver; and 
 a keypad unit ( 276 ) to enable entering control commands to the remote control unit; 
 
 wherein the electro-optical optic sight unit is adapted to receive control signals from the remote control unit. 
 
     
     
       2. The optic sight assembly of  claim 1 , further comprising at least one motion sensor ( 219 ) to sense motion of the optic sight assembly and to issue a signal indicative of the motion to the optic sight controller. 
     
     
       3. The optic sight assembly of  claim 2 , wherein when the input from the motion signal is one of: a signal exceeding a predefined level or a series of signals matching a predefined pattern of signals, the state of the optic sight assembly may be changed from dormant to active. 
     
     
       4. The optic sight assembly of  claim 1 , wherein the angle α is in the range of 15° 30°. 
     
     
       5. The optic sight assembly of  claim 1 , wherein the at least one first control button is adapted to enable control of at least one of turn on/turn off the optic sight assembly and change a brightness of the reticle image. 
     
     
       6. The optic sight assembly of  claim 4 , further comprising a second control button ( 216 ,  330 B) disposed on the rear side of the optic sight assembly substantially in a middle of the rear side of the casing. 
     
     
       7. The optic sight assembly of  claim 6 , wherein the second control button is adapted to control at least one of sleep mode on/off, night vision mode on/off, sleep mode timer. 
     
     
       8. The optic sight assembly of  claim 1 , further comprising a port disposed on a front end of the casing, the port adapted to enable serial communication with the controller unit of the optic sight unit and to provide charging power to a rechargeable battery of the optic sight assembly. 
     
     
       9. The optic sight assembly of  claim 8 , wherein the port is a USB port. 
     
     
       10. The optic sight assembly of  claim 9 , wherein the port is adapted to enable a remote computing unit connected via the port to modify values of the optic sight assembly. 
     
     
       11. The optic sight assembly of  claim 10 , wherein the values are at least one of sleep mode timer value, low battery warning time and levels of reticle brightness. 
     
     
       12. The optic sight assembly of  claim 1 , wherein the remote control unit is installed on the front part of the rifle such that a radiation beam from the remote control transmitter ( 280 ,  404 ) is aimed towards the optic sight unit, wherein the angle of the radiation beam is 10°. 
     
     
       13. The optic sight assembly of  claim 12 , wherein control commands entered at the remote control unit are coded on the radiation beam. 
     
     
       14. The optic sight assembly of  claim 13 , wherein a coding of the control commands is unique to the optic sight unit and to the corresponding remote control unit.
